Canadian Solar Debuts TOPCon 3.0 Module With 24.8% Efficiency

The module utilizes large-format rectangular cells and multi-cut technology to maintain a standard footprint of 2382 × 1134 × 30 mm, simplifying logistics and system integration. By incorporating cell poly-patterned technology, the design achieves bifaciality rates of up to 90%, providing a measurable boost to system-level energy yields.

Engineers at Canadian Solar focused on durability in extreme climates by lowering the temperature coefficient to -0.26%/°C. This advancement, coupled with enhanced passivation, limits annual degradation to 0.35% after the initial year, ensuring an output of over 88.85% across a 30-year lifespan. For specialized environments, the portfolio offers modular upgrades including anti-glare glass and IoT-enabled junction boxes.

"With the launch of our TOPCon 3.0 module, we continue to advance high-efficiency PV technology," said Dr. Shawn Qu, Executive Chairman and Chief Technology Officer. He noted that the design translates into a 1.6% energy yield increase and a 1.4% reduction in Levelized Cost of Electricity. The company will display the technology at Intersolar Europe in Munich from June 23 to 25.
